CUTTING AND FOLDING MACHINE.

Specification of Letters Patent.

Application filed October 16, 1967. Serial No. 397,623.

To all 'whom t may concern:

Be it known that l, RALPH O. SEYMOUR, a citizen of the United States, and resident of Larchmont, in the county of Westchester an d State of New York, have invented a new and useful improvement in Cutting and Folding Machines, of which the following is a specification.

The object of my present invention is to materially simplify the means for assembling, cutting and folding sheets fed from a web which means comprises rotary cutters mounted within the folding cylinders, the parts being so arranged that the operation of the folding devices and the rotary cutters will be properly timed with respect to each other.

Furthermore, the parts are so arranged that the folding off of a predetermined number of sheets is accomplished ,which sheets are combined and delivered to the desired point.

rlhis invention is particularly directed to means for wrapping the web around one of the folding cylinders and then cutting the web to form a collected group of sheets and folding the said group of sheets together and delivering them to a predetermined point.

A practical embodiment of my invention is represented in the accompanying drawings, in which-` Figure 1 represents in side elevation the portion of a cutting and folding machine to which my invention is directed., this view showing the geared connections at one side of the machine, 2- is a detail horizontal section taken in the plane of the cutter and cylinder shafts, Fig. 3 is a detail vertical section taken in the plane of the line A-A of Fig. 2, looking in the direction of the arrows, Fig. 4 is a similar view taken in the plane of the line B-B of Fig. 2 looking in the direction of the arrows, Fig. 5 is a broken section taken in the plane of the line O of Fig. 2 looking in the direction of the arrow, and Fig. 6 is a fragmentary view showing the mechanism for controlling the opening and closing of the grippers on the transfer cylinder.

The side frames of so much of a cutting and folding machine as will be necessary to give a clear understanding of my in'ention are denoted by 1 and 2. These side frames are rozided, respecti'. ely, with inwardly eX- ten ed cylindrical lugs 3, 3*, and 4, 4*, through which the rotary cutter shafts 5 and 6 extend in parallelism with each other, the shaft 5 being eccentrically mounted in its lugs 3 and 4. The cutter shaft 6 is rovided with geared connections 7, 8, with t e cutter shaft 5, the proportions of the gears being such that the cutter shaft 5 will be rotated twice to eery one re'folution of the cutter shaft 6. The cutter shaft 5 carries two cutter blades 9, 10, arranged diametrically apart and the cutter shaft 6 is provided with a reel 16 hazing two cutter blades 11 12, arranged ninety degrees apart so that during two revolutions of the cutter shaft 5, the blades 12, 10, and the blades 11, 9, will coact once.

The folding cylinder within which the rotary cutter 5, 9, 10, is eccentrically mounted, is denoted by 13 and has its hubs 14, 15, mounted to rotate on the cylindrical lugs 3 and 4. The folding cylinder within which the rotary cutter 6, 16, 11, 12, is mounted is denoted by 50 and has its hubs 51, 52, mounted to rotate on the cylindrical lugs 3*, 4*. These two folding cylinders are in parallelism with each other but out of parallelism with the rotary cutters.

The periphery of the folding cylinder 50 is one-third greater than the periphery of the folding cylinder 13 and the two cylinders are driven at the same surface speed so that the cylinder 50 rotates one re' 'elution to one and one-third revolutions of the folding cylinder 13. The geared connection between these two cylinders 50, 13, is denoted by gears 17, 18, mounted respectiely on the hubs 51, 14 of the said cylinders. The folding cylinder 13 is provided with three slots 19, 20, 21, arranged at equal distances apart in its sides through which slots the blades 9 and 10 of the eccentrically mounted rotary cutter 5, 9, 10, are caused to extend to coact with the blades of the rotary cutter 6, 16, 11, 12, at predetermined times. The folding cylinder 50 is provided with a floating folding blade 22 land the folding cylinder 13 is proided with three floating folding grippers 23, 24, 25, arranged to coact at redetermined times with the floating folding lade 22 of the folding cylinder 50. These folding de'1;ices are of the well known floating type, the boX cam 26 for controlling the floating of the grippers as they are brought successively into position opposite the folding blade being mounted to rotate on the stud 4 of the frame and driven at the same speed as the said blade through the geared connection 27, 28, the gear 27 being on the cam 26 and the gear Patented Dec. 29, 1908.

The l relative speeds of thev several parts are'sich that the Ycuttersand the' folding devices are' caused to1I coact.everyV one and one-third revolutions' of Vthe c'yli'nder'13, the" folding cylinder 50 being" that the rotarycutter Within the cylinder 13 rotates tWo `revolutions for every one revolution of the cutter mounted to rotate Within theffolding cylinder 50.
